Vulva

What is the vulva?

Your vulva is another name for your genitals. It’s the area between your legs that allows you to menstruate, give birth, pee and experience sexual pleasure. Although vulvas are an essential part of female anatomy, many people don’t even know the word. Instead, they use “vagina” as a catch-all for all the pleasure-producing parts related to female reproductive anatomy.

But your vulva includes so much more than your vagina. Understanding your vulva can improve your sex life and your overall health.

What is the function of the vulva?

“Vulva” is derived from a Latin word meaning “covering.” Your vulva houses key internal reproductive organs, protecting them from injury. But your vulva does more than provide cover. It’s essential in its own right.

Your vulva plays a role in:

• Sexual pleasure: Your vulva includes organs, openings, blood vessels, nerves and erectile tissue that exist solely to allow you to experience sexual pleasure. Stimulating the vulva is key to orgasm for most females.
• Reproduction: Sperm enters your body through your vaginal opening, allowing fertilization and pregnancy to occur. Your vaginal opening is located inside your vulva. Babies enter the world through the very same vaginal opening during childbirth.
• Menstruation: You shed your uterine lining each month as part of your menstrual cycle during your reproductive years. Period blood exits via your vaginal opening.
• Peeing: Pee (urine) exits your body via your urethra, a tube attached to your bladder that ends at your urethral opening, which is part of your vulva.

Where is your vulva located?

The word “genitals” refers primarily to your external sex organs, what you’d see if you used a handheld mirror to take a look at what’s between your legs. But when it comes to your vulva, the anatomy isn’t so straightforward. For example, you can look into a standing mirror straight on and see the V-shaped patch of skin called your pubic mound or “mons.”

Also, what you see when you look at your vulva through that imaginary handheld mirror depends on processes inside your body, too. Here are the key parts of your vulva to know about and where they’re located.

Pubic mound (“mons veneris,” “mons pubis” or “mons” for short)

Your mons is named after Venus, the Roman goddess of love, beauty and fertility. This is the plump V-shaped patch of skin that extends from the top of your pelvic bone to where your thighs meet. From puberty onwards, pubic hair grows on your mons.

Your mons absorbs impact during penetration. For some people, pressure on the mons during arousal can stimulate sensitive tissue, causing pleasurable sensations. Others might not feel anything or might experience painful sensations.

Labia majora (outer labia/lips)

Pubic hair also grows on your outer lips. These two vertical “lips” are actually plump skin folds that encase the innermost parts of your vulva. They’re filled with erectile tissue that becomes engorged (filled with blood) when you’re aroused. They come in different shapes and sizes for everyone.

Labia minora (inner labia/lips)

Your inner lips are hairless, vertical “lips” inside your outer lips. They start above your clitoris and extend downward to the patch of skin between your vaginal opening and anus (perineum). Some people refer to the uppermost part as the “clitoral hood.” It houses and protects your highly sensitive clitoris. It can diffuse some of the sensation from your clitoris so that clitoral stimulation feels pleasurable instead of painful during sex.

Like your outer lips, inner lips come in many varieties. Some are symmetrical. Others aren’t. Some are tucked inside the outer lips, while others stick out and hang down. Like your outer lips, your inner lips are highly sensitive and fill with blood when you’re aroused.

Clitoris

A roughly pea-sized portion of your clitoris called the glans is underneath your clitoral hood. Your clitoris is the pleasure center of your anatomy. According to a recent study, it contains more than 10,000 nerve endings — more than any other part of the human body. Most people with a clitoris require direct or indirect clitoral stimulation to experience orgasm. Still, the clitoris is so sensitive that too much pressure (or even touching it directly) feels painful for some people.

If you hold the glans between your thumb and pointer finger, you can feel the shaft of your clitoris. This part extends into your body and connects to the internal parts of your clitoris.

Urethral opening

Just below your clit is the urethral opening. This is where pee exits your body via your urethra, the tube that carries pee from your bladder.

Important structures associated with your urethral opening include Skene’s glands. They’re also called “the female prostate” because they produce a milky substance similar to ejaculate in males. This substance lubricates your urethral opening when you pee, preventing urinary tract infections (UTIs).

Your urethral sponge (spongy tissue surrounding your urethra) is another important structure to know about. Pressure on the part of your urethral sponge near the front of your vaginal wall inside your vagina feels pleasurable to some people. This area is sometimes called the “G-spot.” In some people, stimulating this area can cause Skene’s glands to release the milky fluid. The release is more commonly called “squirting.”

Vaginal opening

Your vaginal opening is below your urethral opening. Your vagina is a flexible, muscular canal inside your body that allows you to menstruate, become pregnant and give birth. The outermost one-third of your vagina (the portion commonly associated with your vulva) is filled with highly sensitive nerve endings that usually produce pleasurable feelings when touched.

Other important related structures may include a hymen, a delicate membrane that sits over part of your vaginal opening. It can tear during your first experience with penetration like a tampon or sex, or even from some exercises.

Your Bartholin glands are also important. They’re located at the entrance of your vagina and secrete fluid that helps keep your vagina lubricated. The lubrication makes contact with your vagina and vulva feel more pleasurable than painful during sex. But Bartholin glands don’t do all the work. Skene’s glands and secretions from your vaginal wall also keep you lubricated.

What are the common conditions and disorders that affect your vulva?

Infections and skin conditions are the most common conditions that affect your vulva. Given your vulva’s role in helping you pee and have sex, it’s a given that common conditions include urinary tract infections and sexually transmitted infections (STIs).

Infections

• Bacterial vaginosis: An infection caused by an overgrowth of Gardnerella vaginalis bacteria.
• Chancroid (soft chancre): An STI caused by a bacteria called Haemophilus ducreyi.
• Chlamydia: The most common STI, caused by a bacteria called Chlamydia trachomatis.
• Gonorrhea: An STI caused by a bacteria called Neisseria gonorrhoeae.
• Granuloma inguinale (donovanosis): An STI caused by a bacteria called Klebsiella granulomatis.
• Hepatitis B: An infection caused by the hepatitis B virus.
• Hepatitis C: An infection caused by the hepatitis C virus.
• Herpes: An STI caused by the herpes simplex virus.
• HIV: An STI caused by the human immunodeficiency virus.
• HPV: An STI caused by the human papilloma virus. Some strains of the virus can lead to cervical cancer, while others can cause genital warts.
• Syphilis: An STI caused by a bacterial called Treponema pallidum.
• Trichomoniasis: An STI caused by a parasite called Trichomonas vaginalis.
• Urinary tract infection: Any type of infection in your urinary tract, but UTIs are most commonly related to Escherichia coli (E. coli) bacteria.
• Yeast infection: An infection caused by an overgrowth of a fungus called Candida.

Skin conditions

• Folliculitis: Infection or inflammation that happens when you get an in-grown pubic hair. It usually looks like a bump.
• Lichen sclerosus: Skin condition that causes inflammation, itching and pain on your vulva.
• Pubic lice (crabs): Tiny insects that live in your pubic hair that can be transmitted during sex.
• Scabies: An itchy rash caused by the Sarcoptes scabiei var hominis mite.
• Vulvitis or vaginitis: Inflammation in your vulva or vagina that may be related to infection, irritation or injury.

Other conditions

• Bartholin cyst: A fluid-filled lump that forms when a Bartholin gland becomes blocked.
• Dyspareunia: Pain during or after penetrative sex.
• Imperforate hymen: A condition you’re born with where your hymen completely covers your vaginal opening.
• Labial adhesions: A condition that causes your inner lips to fuse together instead of remaining separate.
• Vulvar cancer: Rare cancer that can form on your vulva. It’s usually related to lichen sclerosus or an HPV infection.
• Vulvodynia: Pain in your vulva that doesn’t have a clear cause.

What are the common signs or symptoms of a condition affecting my vulva?

All vulvas generally have the same parts. Still, no two vulvas are the same. This is why it’s so important to familiarize yourself with your vulva, so you recognize changes that may signal a condition. Get to know how your vulva typically looks and smells. Pay attention to the fluids your vagina secretes at various points during your menstrual cycle. Familiarize yourself with the sensations you feel when using your vulva — peeing, menstruating or having sex — so you know what’s typical for you.

Changes signaling a condition affecting your vulva may involve your:

• Skin: Changes to the skin on your vulva, like a lump or bump, may signal a Bartholin cyst, genital warts (caused by HPV) or folliculitis. Itching, inflammation and swelling may be signs of an infection. Or you may be sensitive to a particular irritant, like a chemical in a period product.
• Peeing frequency: Peeing more or a burning sensation when you pee may be a sign of a urinary tract infection or an STI.
• Vaginal discharge: A healthy vagina secretes clear, white or off-white fluid. Changes in the color, texture or odor of your vaginal discharge may signal an infection or another condition.
• Vaginal odor: Healthy vaginas have slight odors that can change at various points during your menstrual cycle. This is normal. An unpleasant odor, though, like a fishy or musty smell, is something you should get checked. You may have an infection.
• Sex life: Pain during sex may be a sign of decreasing estrogen levels or a condition like vulvodynia. Sometimes, pain is a sign that you need medication or to change your approach to sex.

Changes to your vulva are common during menopause, the period in life when you stop getting your periods. During menopause, estrogen levels drop. The decrease can lead to vaginal dryness and thinning pubic hair. You may notice less fatty tissue in your vulva and experience pain during or after penetrative sex.

Talk to your provider if you’re noticing changes in your vulva. You don’t have to live with discomfort or feel embarrassed. There are treatments and lifestyle changes that can help.

What are some tips for caring for my vulva?

You can prevent many of the conditions that affect your vulva by keeping your vulva clean, dry and free from irritants. Since irritation and infection often involve your vagina, too, good vulvar care also keeps your vagina healthy.

To care for your vulva:

• Wash regularly with mild soap and warm water. When it comes to vulvar care, it’s important not to overdo it. Your vagina contains good bacteria that keep your vagina clean and healthy. Overwashing can disrupt the balance of good bacteria and lead to infections.
• Avoid douching, which can upset the natural balance of organisms in your vagina.
• Avoid laundry detergents or menstrual products that contain harsh ingredients. This includes avoiding fabric softeners and detergents with enzymes (amylase, lipase, protease and cellulose) and perfumed or scented soaps, sprays, deodorants or tampons.
• Wear cotton underwear instead of nylon, which can trap heat and moisture, providing an ideal environment for organisms that can cause infection.
• Change out of bathing suits or sweaty workout clothes ASAP to prevent infections. Wash them between uses.
• Don’t leave tampons in for longer than eight hours. Doing so can put you at risk of toxic shock syndrome.

Protecting yourself from STIs is an essential part of caring for your vulva. Learn about how various STIs spread. For example, some STIs, like HPV, spread through skin-to-skin contact. Other STIs — like chlamydia and gonorrhea — spread through body fluids, including vaginal fluid and semen. Understanding how various STIs spread can shape how you practice safer sex in the bedroom and protect your vulva.
